Baby{40 s napkin

ABSTRACT

The invention concerns a napkin to be thrown away which comprises a backing and a first impervious layer, both being provided with two apertures and located against an absorbing layer. A second impervious layer is provided in order to house this absorbing layer between said first and second impervious layers. Furthermore, the backing is provided with lateral recesses so as to conform closely to the shape of the body and around legs of a baby in order to ensure tightness between the baby&#39;&#39;s body and the napkin.

This throw away napkin is characterized by the fact that it comprises abacking and a first impervious layer provided with two apertures,located against an absorbing layer and a second impervious layerconfines this absorbing layer between two impervious layers and by thefact that this backing comprises two lateral recesses enabling thenapkin to be closely adapted to the body.

The attached drawing shows schematically and by way of example oneembodiment of the napkin accordingto the invention.

FIG. 1 shows the use of a napkin.

FIG. 2 is a view of it in longitudinal cross-section.

FIG. 3 is a view partially cut away of a second embodiment of thenapkin.

FIG. 4 is a plan view of the backing of the napkin shown at FIG. 3. g

The napkin shown at FIGS. 1 and 2 presents seen from above a generallyrectangular shape and is constituted by a backing or strip 1 the twoends of which 2, 3 emerge from the stack of the layers of the napkin butthe width of which is smaller than that of the other layers. Thisbacking 1 is provided with at least one hole or aperture 4, 4a in theexample shown.

This backing is covered on one side by a first layer 5 of a smoothmaterial which is permeable such as paper cloth and on the other sidewith a first impervious layer 6 for example of plastic material orcellulosic material. These two layers 5 and 6 comprise also apetureswhich correspond to the apertures 4 and 4a of the strip 1.

Finally the napkin comprises further, located between the firstimpervious layer 6 and a second impervious layer 7 a second absorbinglayer constituted in the example shown by a layer of paper cloth 8 and apartial layer 9 of cellulosic wadding or hydrophilic cotton. This secondabsorbing layer comprises also apertures corresponding to the apertures4 and 4a of the strip 1. s

The mounting together of the stack thus obtained may be effected by aslight gluing of the layers the one on the other or simply bycompression. However, the second impervious layer 7 is glued along theperiphery of the first impervious layer 6 so as to form under it a kindof relatively tight pocket.

It is to be noted here that the layer 7 may be greater or wider than thelayer 6 so as to constitute a pocket and to prevent during the settingin place of the napkin the compression of the absorbing layer 8, 9.

In the embodiment shown the second impervious layer 7 is larger than therest of the napkin and is provided with self-gluing strips 10 whichpermit one to wind it and to fix it around the legs and the body of ababy just as a trousers.

The ends 2, 3 of the strip cooperate in the example shownwith asuspender 11 passing over the shoulders, around the neck of the baby inorder to maintain the napkin in place. To this effect the ends 2, 3 maybe provided with anchoring means or regulating means enabling a perfectadjustment of the napkin.

The napkin is placed so that the urine of the baby be' directed towardsthe opening 4a towards the second absorbing layer 8, 9 in the area of itwhich comprises a great thickness of absorbing material 9 whereas theexcrements of the baby'are directed through the aperture 4 in an area ofthe absorbing layer 8, 9 constituting a pocket or container with thesecond impervious layer 7.

Thus not only the urine but also the excrements of the baby arecollected and accumulated in the second absorbing layer 8, 9 locatedbetween two impervious layers 6 and 7 and this enables an efficientprotection of the baby.

In the second embodiment shown in FIGS. 3 and 4 the napkin is similar tothe one described above, that is, it comprises a first impervious layer6 and a second impervious layer 7, this latter constituting a pocket,for example of a plastic material. These impervious layers 6, 7 aresecured together along their periphery so as to constitute an envelopeholding the backing 1 and the second absorbing layer constituted here byonly one layer of cellulosic wadding or hydrophile cotton 12 having anapproximately constant thickness. The first absorbing layer 5 is locatedon top of the first impervious layer 6 outside the envelope constitutedby the layers 6 and 7.

In this embodiment the ends 2 and 3 of the backing l are located insidethe envelope constituted by the tight layers 6, 7 but all the stackconstituting the napkin is provided with holes 13 permitting the hookingof a suspender 14 for the fixing of the napkin.

Holes 4 and 4a are provided in the upper absorbing layer 5 in thebacking l and inthe second absorbing layer 12.

Finally the backing 1 comprises lateral recesses 15 enabling to thenapkin to lie closely against the body I between the legs to avoid thatthe urine and the excrements escape between the skin and the napkin.

The backing 1 comprises further an opening 16 and slots 17 which permitshaping the backing and thus the napkin so that it follows as closely aspossible the shapes of the baby and can be inserted between itsbuttocks.

Numerous variants may be realized without departing from the scope ofthe claimed protection. Particularly the strip 1 as well as the layers5, 6, 8 and 9 may comprise a different number of openings 4. The thickabsorbing layer 9 could extend over the whole length of the napkin, andcomprise only one or two apertures.

The impervious layer 7 could be of the same dimension as the otherlayers in which case the napkin would be maintained in place only by thetwo ends 2, 3 of the strip 1 fastened to the suspender. In this case andif the two impervious layers 6, 7 are of plastic material it is possibleto secure them along their periphery enclosing thus completely thesecond absorbing layer 8, 9 in a tight housing.

The layer 6 could be larger than the other ones and be used for thefixing of the napkin to the suspender.

Finally the strip 1 could in certain cases replace the first imperviouslayer. In fact, one may conceive with plastic material, that a tightsheet, constituating the impervious layer 6 has a central reinforcedportion and an extension in the longitudinal axis of the napkin toconstituate the backing l.

An important characteristic of the napkin is that it is easily appliedto the body and can be closely applied there against in liquid-tightrelationship.

ln a variant the napkin could be provided with powder, that is to saythat its free surface of the first absorbing layer could be covered by athin layer of talc.

The opening 4a provided in the backing can be greater than thecorresponding openings in the first absorbing and liquid-tight layer sothat the edges of this aperture 4a which could be harmful are covered bya smooth protection.
